php.ini file

Does the php.ini file need to be renamed from php.ini.production to php.ini and modified in order to use phpAzure? When using the sample code (shown below) to create a simple container on the live Azure service, I recieve the error message
outlined below... I've uploaded the appropriate web.roleConfig file pointing FastCGI to %RoleRoot%\php\php-cgi.exe (and it does exist),
but never-the-less, it errors out saying it's unable to load cURL.

Is it necessary to modify the php.ini under my PHP install directory and uncomment the line 'extension=php_curl.dll'?
